ABSTRACT --- Recent advances in scrap processing, melting, metal treatment, and
casting technologies have a major impact on the economics of recycling aluminum
extrusion scrap. Technologies that permit rapid charging, melting, and melt preparation,
are combined with processes that remove potential pollutants and particulates, refine the
melt, and cast uniform ingot structures. The resulting facility is capable of producing a wide
range of alloys and ingot sizes with minimum inventory levels while operating at high levels
of productivity and energy efficiency. The facility is intrinsically safe to operate and meets
all current and near-term environmental standards.
